BUILDING-WALL.

Specification of Letters Patent.

Application filed September 26, 1906- Serial No. 336,36L

To all whom it may concern:

Be it known that 1; WILLIAM CURL TT, 'a

' citizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented new and usefulImprovements in Building-Walls, of which the following is aspecification.

My invention pertains tov walls of hollow building blocks and itcontemplates the provision in such a wall of simple, inexpensive,

and easily applied means for strongly connecting the meeting ends of twoblocks together and at the same time holding the intermediate portion ofa superposed block to and in vertical alinement with the lower blocks.

With the foregoing in mind, the invention will be fully understood fromthe following descriptionand claims when the same are read in connectionwith the accompanying drawings, forming part of this specification, inwhich:

Figure 1, is a side elevation illustrating the I clip comprised in myinvention as connecting the meeting ends of two blocks, and holding thecenter of a block arranged over the joint between the lower bloclis.Fig. 2 is'a transvense section takenin the plane indicated by the line2-2 of Fig. 1,. Fig. '3 is a horizontal section taken in a plane abovethe clip. Fig. 4 is a perspective view of the clip removed. Fig. 5 isaperspective view of a modified clip.

Fig. 6 is a transverse section showing the modified clip in use.

Referring by letter to the said drawings, and more particularly to Fi s.1 to 4 thereof:

A A are hollow building b ocks'or tiles arranged end to end, Fig. 1. Bis a similar hollow block or tile arranged with its intermediate portionabove the 'oint between the lower'blocks or tiles, andis my novel clipfrom the ends of said body, an

for connecting the meeting ends of the lower blocks together and holdingthe upper block above the joint between the lower blocks:

The said clip C is preferably,.though;not necessarily, formed in-any:approved jwa 'of' sheet-metal; andit comprises'a flat b0 y a, flanges breaching upward at ri ht angles.

reaching downward at right angles from the intermediate portions of thelongitudinal edges of body a. I

' In the practice of my invention, the blocks-- A are arranged end toend as shown, and the clip 0 is placed over the'meeting-end portionsPatented May 28,1907.

said end portions while the depending flanges 9 rest snug againsttheinner sides of the endporions, this to tightly and strongly holdv theends of the blocks together. The upper block B is then positioned sothat its intermediate portion rests over the body a of the clip, andabove the joint between the lower blocks, and snugly between theupwardly extending flanges b of the clip, when, as will be readilyapparent, the upper block will be strongly held in alinement with thelower block and against casual lateral displacement in either direction.This operation is continued throughout the building of the wall; auditwill be appreciated that not only are the clips C adapted to be quicklyand easily placed in position, but are calculated to facilitate theplacing of the intermediate portions of the upper blocks over the jointsbetween the blocks on which the upper blocks are superposed. vIt willalso be appreciated that by connecting the meeting ends of the lowerblocks together and holding the intermediate portions of the upperblocks, the clips 0 contribute materially to the strength and durabilityof the wall. w

The modified clip C shown in Figs. 5 and 6, comprises a flat body a,upwardly direct: ed, right angle flanges b at the ends of the body, anddepending righ't angle flanges c on the longitudinal edges of the body.It will be noticed, however, that the ends of the flanges 0' rest in thesame vertical planes as the endflanges b, and from this it follows thatwhile the flanges c will connect the end portions of two lower. blocks Ato other in the'same manner as the flanges c o the clip (3, the endflanges b will hold the intermediate portion of the superposed block Bby bearing snug against. the inner sides of the side walls of saidblock.

. It will be gathered from the foregoingthat v While it is moreexpedient to form the clips 0 and C of sheet-metal, yet said clips maybe made of any other material compatible with .myinvention withoutinvolving departure from the scope thereof. The constructions hereinshown and described constitute the preferred embodiments of myinvention, but I desire it understood that in practice such changesin'the for'm,'construction',and relative arran ementof parts maybefmadeas fairly fall wlt 1n the I scope of my invention asclalmed Q seaeee ofthe lower blocks and between the upper edges of said end walls and theupper block,

arms reaching downward at right angles from the body an arranged at theinner sides of the adjacent end walls of the lower blocks to hold saidblocks together or against endwise I movement away from each other, anarm reaching upward at a right angle from one end of the fiat body andopposed to one side of the upper block,'and an armreaehing upward at aright angle from theopposite end of the flat body and opposed to theopposite side of the upperbloek; said upwardly reaching arms beingadapted to hold the upper block against lateral displacement.

, 2. A wall comprising lower, hollow blocks arranged end to end, anupper, hollow block arranged with its intermediate portion above themeeting ends of the lower blocks, and a clip arranged entirely betweenthe vertical planes of the outer sides of the blocks and having a flatbody resting on the adjacent end walls of the lower blocks and betweenthe upper edges of said end walls and the upper block, arms reachingdownward at right angles from the body and arranged at the inner sidesof the adjacent end walls of the lower blocks to hold said blockstogether or against endwise movement away from each other, an armreachingupward at a right angle from one end of the flat body andopposed to the inner side of one side wall of the upper block, and anarm reaching upward at a right angle from the opposite end of the flatbody and opposed to the inner side of the opposite side wall of theupper block, for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
